' Application filed July 2, 1928. Serial No. 648,958.. 2

The invention relates to printing presses, and more especially to novel and useful improvements 1n intaglio printing presses.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained .by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described. ,1 a

The accompanyin drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles'of the invention.

Of the drawings Fig. 1 is a side elevation, partly diagrammatic, and with certain parts omitted, of a. printing press embodying the invention;

Fig. 2 is a fragmentary end elevation,

:. corresponding to the lower left-hand end of Fig 1;

Fig. 3 is a view similar to Fig. 2, but showing a different arrangement of printing cylinders;

Fig. 4 is an enlarged transverse vertical section, taken substantially on the line 4-4 of Fig. 2; and i Fig. 5 is an enlarged horizontal fragmentary section, taken on the line 5-5 of Fig. 2. Referring now to the embodiment of the invention illustrated by way of example in the accompanying drawings, a web supply roll 1 is mounte on a carriage 2, having wheels 3 running on a track 4, formed in the bed of the machine. I extra paper supply roll, carried on a like carriage 6, mounted on wheels 7, running on a guideway 8, carried by the machine frame. This represents a convenient paper supply, although such supply may be of any known or suitable form so far as concerns the present invention. Only one web of paper is led through the press at a time.

i The web a: is led over any number of suitably positioned guiding rollers 14 and 15, and over the mechanism 16, which is preferably a device for regulating the feed or the web, but is indicated only generally herein as it constitutes in itself no part of the present invention. The web then passes over a 5 represents anguide roll 17, ,and goes to impression between the impression cylinder 18 and the intaglio form cylinder 19, constituting the members of a printing couple. The web passes thence over other suitably placed guide rollers 20 and 21, and around a drymg cylinder 22. Additional guide rollers 23, 24 and 25 are provided, and preferably a web feed regulating device 26. The web then passes around guide rollers 27 and through the impression between impression cylinder 28 and intaglio cylinder 29 to'perfeet the web.

The web then passes over a guide roll 30 and around dryin cylinder 31, past other suitably placed guide rollers '32, 33, 34, and 36, and past a registering or feed regulating device 37 The Web then passes to 1mpress1on between an impression cylinder 40 and an intaglio cylinder 41 to be again printed. It then passes around a guide roller 42, and around a drying cylinder 43, and then over a series of guide rollers 44, 45, 46, 47, 48, 49 and 50 and thence-to a folding mechanism indicated generally by 51.

The foregoingrepresents one general arrangement of a perfecting or multi-color intaglio press, and so far as the present invention is concerned, this general mechanism may be of any desired known or suitable form. i 1

The present invention is directed to auxiliary printing means designed to print only a portion of the entire area which is printed by the full intaglio cylinder or cylinders. A press embodying the invention is capacitated to print in'a'supplemental color upon a portion of the design printed by the mam cylinders, or to add an impression to the original impression of said cylinders. It is further especially designed to provide means whereby on pages may be changed or substituted without disturbing the remainder of the desi which it is desired to perpetuate, and wit e or-more intaglio-printed I out requiringthe removal from the pres of the entire mam or original cylinder, and reetching and otherwise preparing such cylinder. A particular portion of the original design ma be removed from the main cylinder, an the smaller cylinder be positioned to print the substituted design in the corresponding place on the paper.

In the preferred illustrated embodiment of the invention, one vor more narrow width cylinders are provided; they are placed at the left hand end of the press of Fig. l; in Fig. 2, a half-width cylinder 58 being shown, and in Fig.3 two quarter-width cylinders 59 and 60 are shown. These respective cylinders are slidably positionable along the corresponding shafts, 61 for cylinder 58, and shaft 62 for cylinders 59 and-60. These cylinders are made to rotate with their shafts by suitable means, such as feathers or splines 63, but leaving the cylinders longitudinally shiftable along their shafts. The cylinders are held in desired position along their shafts by suitable means, such as clamping screws 64.

Thus these partial-length cylinders may be shifted along their respective shafts as desired, the cylinder 58 being shiftable onto either half of the full width web, or may be positioned centrally on its shaft. The quarter cylinders 59 and 60 are shiftable independently of each other onto any desired quarters of a full width web. While narrow webs m, m and m are shown in Figs.

2 and 3, it will be understood that the device will be ordinarily used with a' full-width web g}, which has been printed upon by the preceding full-width cylinders. For instance, the cylinders 19 and 29 may be regarded as being of full width and printing upon the full width of the web a:, and either the cylinder 58 or the cylinders 59 and 60 may be regarded as printing upon any twq quarters, or other parts, of the full-width web., This, as already stated, would be in addition to the printing already made by one of the full-width cylinders, or upon a spaceor spaces left vacant upon the full-width intaglio cylinders, either originally or by etching it away afterward. These cylinders 58, or 59 and 60, would be placed, at the left end of Fig. 1, substantially where cylinder 40is shown. The cylinder 40 may extendthe full width of the web, as in Fig. 2; or a plurality'of narrow cylinders 40 may be used, as in Fig. 3.

The inking mechanism in its general features may be of any known or suitable form, and as shown the ink fountains or troughs 67, 68 and 69, respectively, are of widths corresponding to the respective intaglio cylinders 58, 59 and 60, although if desired a fountain of the full Width of the press may th be used.

To provide for the positioning of the narrow width inking fountains transversely to the press, and corresponding to the position of the intaglio cylinders, each of these fo'untains is provided with a channeled bottom, having downwardly extending flanges 70 and 71, which fit over either side of, and are slidable along, a horizontally-disposed and upon which the fountain rests. Qne or more clamping screws 72 may be provided to maintain the fountain in proper position upon the bar 73. The various inking fountains will be provided with doctor blades 7 4 or equivalent devices. 1

Means are provided for vertically variably positioning the ink fountain, and for letting it down from the intaglio cylinders and raising it again thereto. In the embodied form thereof, the respective supporting and guiding bars 73 are provided with dove-tail guide-engaging portions 7 8 at the ends thereof, these portions sliding within verticallydisposed pairs of guideways 7 9 and 80, fixed to the machine frame. At either end thereof, each guiding and supporting bar 73 has screw-threaded connection with, and is supported on, vertically disposed screw shafts 81 and 82, respectively, which are journaled in lugs 83v and 84 projecting from the uprights of. the machine frame.

Collars 85 and 86 maintain the screwshafts against longitudinal displacement with respect to their mountings. The screw shafts are provided at their bottom ends, respectively, with beveled gears 87 and 88, which mesh, respectively, with bevel gears 89 and 90. These gears are fixed on a shaft 91, which shaft is journaled in bearings 92 and 93, fixed to and projecting upwardly from the bottom frame plate of the press.

Any suitable means for turning the screw shaft 91 may be provided, and a crank handle .94 is shown fixed to one end of the shaft for this purpose.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.
